JOHN NICHOLSON, or HOUSTON, TEXAS.

HYDROCARBON-BURNER.

To all whom t may concern:

Be it known that I, JOHN NIcHoLsoN, a

citizen of the United` States, residing at Houston, inthe county ofHarris and State of Texas, have invented certain new7 and usefulImprovements in Hydrocarbon-Burn-` ers, of which the following is aspecication.

This. invention relates to new and `useful improvements in Oahydrocarbonburner.

The obj ect of the invention is to provide a burner of the characterdescribed which is especially designed for atomizing hydrocarbon,preparatory to burning the same, and is adapted for use in utilizing alow gravity oil or other heavy substances as fuel for locomotives,stationary boilers, kilns, heating furnaces and the like.

' With the above and other objects in view, the invention has particularrelation to certain novel features of construction, arrangementV ofparts, and use, an example of which is given in` this specification` andillustrated in the accompanyingdrawings, wherein:

Figures land 2, aretop and bottom views, respectively, showing thegeneral-contour of the burner. n

Fig. 3, is a horizontal sectional view, taken through the oil chamber.

Fig. 4', is avertical, sectional view, showing both steam and Oilchambers, and

Figs. 5 and 6, show back and front views, respectively, of the burner.

VReferring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures, the numeral1, refers to an oil inlet pipe and the numeral 2, refers to a Steaminlet pipe said pipes being threaded into the burner and entering thefuel and steam chambers 3 and 4, respectively, of the burner 5. Thesteam and fuel chambers are separated by a transverse partition 6, andare relatively narrow at the base or outer end of the burner andgradually flare out toward the nozzle end thereof, and the upper wall ofthe fuel chamber, and likewise the lower wall of the steam chamberconverge, gradually contracting said chambers to a point about midwaythe ends of the burner and said chambers then continue of uniformvertical dimensions to the nozzle end. Depending from the upper wall ofthe fuel chamber' is a transverse baffle 7 whose sides convergedownwardly to an apex and beyond said baiile, toward the nozzle end ofthe burner,

the upper side of the partition; 6 has a plurality of longitudinal ribs8, triangular in cross Section and gradually enlarging from their innerto their out'er ends. These ribs are spaced apart and terminate short ofthe burnernozzle. The nozzle end of the steam chamber is rounded ofi' atthe point 9, and is provided with a transverse slit 10, through whichthe steam issues ina fanlike sheet, and the nozzle end of the upper wallof the fuel chamber has a slight downward curve forming the deilectorl1.

The fuel chamber has two steam inlets 12, 12 at thebase thereof, throughwhich the Vjets Of steam are admitted to said chamber at Vapproximately4:5? angle. Oil is admitted into the fuel chamber through the'pipe l,and the steam jetsmingle withsaid oil, and break up and evenlydistribute the same over the bottom of the said chamber, being deiiectedtowardthe bottom of said chamber, by the baffle 7, and beyond saidbaiiie, will be evenly divided by the ribs 8, passingbetween them and{iowing down over the roundedend of the steam chamber.V The` deflectorll causes a positive deflectionjof the fuel downwardly so as to preventthe pressure in the fuel chamber from blowing the fuel over the sheet ofsteamissuingfrom the slit `l(l,land thus forcing said fuel downwardlyinto said sheet of steam so that the steam and fuel will thoroughlymingle together,

Steam enters the steam chamber 4, through the steam pipe 2, underpressure, the pressure being sufficient to force the steam out throughthe slit l0, in a fanlike sheet and t0 catch up the fuel flowing downover the nozzle end of the steam chamber and thoroughly mingle with andvaporize the same.

What I claim is:

l A burner including a fuel chamber and a steam chamber, fuel and steamconduits entering said respective chambers, the nozzle end of the steamchamber being provided with a transverse slit, and the nozzle end of thefuel chamber having a plurality of longitudinal ribs therein spacedapart triangular in cross section andV enlarging from their inner totheir Outer ends.

2. A burner including a fuel chamber and a steam chamber, fuel and steamconduits entering said respective chambers, the nozzle end of the steamchamber being provided with a transverse slit, the nozzle end. of thefuel chamber having a plurality of Copies of ythis patent may beobtained for longitudinal ribs therein spaced apart, and a transversebaiiie depending from the upper wall of the fuel chamber and locatedbehind the said ribs',

3. A burner including a fuel chamber which flares toward its dischargeend, the upper wall 0f Said chamber declining toward the lower wall, andthe nozzle end thereof being downwardly curved, 'forming a deflector,longitudinal ribs spaced apart and arrangedin the discharge end of thecham ber and a transverse battle depending from the upper wall of thechamber and arranged behind said ribs. 4. A burner including a fuelchamber and -a steam chamber, separatedby a transverse partition, thenozzle end of the steam Ihamber 'being provided with a transverse slit,and the nozzle end of the upper wall of the fuel chamber forming adownwardly curved deliector to deflect 'the fuel issuing from saidburner into the steam issuing fromsaid slit, a `bailledepending from theupper wall of the fuel chamber, and means arranged in the nozzle endthereof for 'sepa rating' the fuel issuing from the nozzle thereof;

A burner including a fuel chamber and a steam chamber separated by atransverse partition, the nozzle end of the steam chamber having atransverse slit through which steam issues, in a fanlike vsheet and thenozzle end of the fuel chamber being formed to direct the fuel issuingtherefrom into the steam issuing from said slit, and a steam inletarranged' at each side of the fuel chamber through which jets of steamare admitted into said chamber t0. mingle with the fuel therein,

6. A burner including` afuel chamber and a steam chamber separated by atransverse partition, the nozzle end of the steam chamber having atransverse slit through which steam issues, in a fanlike sheet and thenoz zle end of the to direct the fuel v.issuing therefrom into the steamissuing from said slit, a steam `inlet arranged at each side of the-fuel chamber through which jets of' steam are admitted into saidchamber to mingle with the fuel therein, and a transverse bailledepending from the upper wall of the fuel chamber in front of said steaminlets.

7. A burner including a fuel chamber and a steam chamber separatedby'atransverse partition, 'the nozzle end of the steam chamber having atransverse slit through which steam issues, lin a fanlijlre sheet, andthe nozzle end of the fuel `chamber being formed to direct the fuelissuing therefrom into the steam issuing from said slit, a steam inletarranged at each side of the fuel chamber through which jets of steamaread'mitted into said chamber to mingle with the fuel therein, andmeans arranged in l the nozzle end of the fuel chamber vforseparatingthe stream `of fuel issuing therefrom,

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
